Question

Dertemine o mmc (maximo multiplo comum) de:

a)mmc (20,18)


b)mmc (36,20)

Answer 1

a) m.m.c. (20, 18)

20, 18 | 2
10, 9   | 2
5, 9     | 3
5, 3     | 3
5, 1     | 5
1, 1     m.m.c. = 2 . 2 . 3 . 3 . 5 = 180

b) m.m.c. (36, 20)

36, 20 | 2
18, 10 | 2
9, 5     | 3
3, 5     | 3
1, 5     | 5
1, 1     m.m.c. = 2 . 2 . 3 . 3 . 5 = 180

Answer 2

A)

mmc (18) = 18,36,54,72,90,108,126,144,162,180...
mmc (20) = 20,40,60,80,100,120,140,160,180,200...
mmc (18,20) = 10,9

B) 

mmc (36) = 36,72,108,144,180,216,252,288,324,360...
mmc ( 20) = 20,40,60,80,100,120,140,160,180,200...
mmc 36,20) = 5,9
